Title: Spark plug for internal combustion engine
Inventor: OSHIMA TAKAFUMI
IPC: H01T13/32
Filed: 1993-07-23
Abstract: PURPOSE:To reduce discharge voltage in plus polarity by making the area of one end surface of an earth electrode to form a spark discharge space part smaller than the area of a jointing part with a subject metal fitting, and jointing a noble metal member to one end surface of the electrode. CONSTITUTION:In a spark discharge part 12 composed of a center electrode 3 and an earth electrode 10, a spark discharge gap part 14 is formed in one or more places out of a side surface part 8 on the tip of the electrode 3 and one end surface 13 as a discharge part of the electrode 10. The area of one end surface 13 to from the gap part 14 is made smaller than the area of a jointing part 15 with a subject metal fitting 9. A noble metal member 19 is jointed to one end surface 13. When the electrode 3 is put in plus polarity by using this simultaneous ignition system, discharge voltage in the electrode 10 can be restrained low, and the area of one end surface 13 to form the gap part 14 is made smaller than the area of the jointing part 15 with the subject metal fitting 9.

Title: Intermittent blow type wind-tunnel test apparatus
Inventor: HASHIMOTO TAKEO
IPC: G01M9/04
Filed: 1989-08-03
Abstract: PURPOSE:To prevent breakdown of a test model due to a vibration load applied thereon when a shock wave on the occasion of a start passes and when flutter occurs, by determining the occurrence of the flutter by a flutter determining device receiving a signal from an acceleration pickup as an input, during a test. CONSTITUTION:The completion of the start of a wind-tunnel is judged by a start determining device 8 receiving a signal from a pressure detector 7 as an input. Based on an output of this device, a switch 13 is opened or closed by a control device 9 to control a current from a power source 12, and thereby an actuator 5 is operated. During a test, the occurrence of flutter is determined by a flutter determining device 11 receiving a signal from an acceleration pickup 10 as an input, and thereby the actuator 5 is operated. In this way, a test model 1 is protected from a vibration load generated when a shock wave on the occasion of the start of the wind-tunnel passes and from divergent vibration generated when the flutter occurs, and thus the breakdown thereof can be prevented.

Title: Client server network system
Inventor: SHIMOZAKA NOBORU
IPC: H04L12/803
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To prevent all terminals under a server from being stopped due to system down and to improve the reliability of the entire network when excessive load is placed on the server. SOLUTION: The server is constituted of plural server terminals 10a which have a server function. In such cases, each server terminal is provided with an overload state supervising part 31 which monitors an overload state of a self-server terminal and notifies the effect when it detects an overload state, a terminal information storing part 33 which registers the server address of each server terminal, a network address selecting part 32 which refers to the terminal information storing part, selects another server terminal that becomes a substitute server for the self-server terminal and notifies the server address of the server terminal when it receives the notification of an overload state,  and a network address converting part 34 which converts the address of a telegraphic message from a client terminal to the self-server terminal into a notified network address and sends it other server terminals when the network address is notified from the network address selecting part.
Patent JP-H0250896-A (JP)
Title: Ic card
Inventor: UEDA SHIGEJI
IPC: B42D15/10
Filed: 1988-08-12
Abstract: PURPOSE:To prevent the break of data accumulated in an IC memory or the like and electronic component parts by a method wherein each of a top-side panel and a back-side panel has a two-layer structure made of an inner metal layer and an outer insulating layer, and the respective inner layers of the both panels are connected with each other in an electrically short state. CONSTITUTION:Each of outer layers 16 of panels 4, 6 is composed of a thick insulating layer. Thus, even if an electrified finger 12 comes into contact with the outer layer 16, electric charges are inhibited from transferring by the insulating layer as the outer layer 16, thereby being absorbed only into a contact part of the finger 12 on the outer layer 16 to remain there without the possibility that the electric charges are absorbed all over the surface to electrify the surface. In this manner, an electric electrification phenomenon at the metal layers as the inner layers 14 of the panels 4, 6 can be inhibited. Therefore, since a voltage of a contact electric discharge is kept low, if occurring, the break of the data accumulated in an IC memory loaded on a printing wiring substrate 8, electronic component parts, such as IC memories, and others due to the electric discharge can be effectively prevented from occurring.

Filed: 1984-09-27
Abstract: PURPOSE:To decrease the number of parts and to eliminate the laboriousness of operation by making common use of one key as a key for selecting paper feed cassettes disposed in two upper and lower stages and a key for selecting paper sizes. CONSTITUTION:A paper size selecting button 61 is provided in a paper feed cassette selecting part 60 so that modes are successively changed over to the upper cassette selecting mode, APS mode (automatic paper selecting mode) and lower cassette selecting mode.

A lower cassette feed routine is similarly started when the operator pushes twice the button. The corresponding paper according to the original and the magnification selected by a magnification change button 53 is selected from the upper of lower cassette when the APS mode is selected. The change-over of the operation is thus made possible with the same key and therefore the operating efficiency is improved.

Title: Communication equipment
Inventor: TOYAMA TAKESHI
IPC: H04M1/2745
Filed: 1988-08-13
Abstract: PURPOSE:To easily revise the specification of a dialing function by providing a 1st means starting dialing automatically and a means making a 2nd means starting dialing operationable selectively in response to a manual input signal. CONSTITUTION:A control section 1 executes the registration mode of service information to write data inhibiting a timeout dialing to a storage section 6 and several digits of binary numbers (service information) and a cursor are displayed on a display device in the service information registration mode. The service information is rewritten by using a ten-key so as to move the cursor to a desired digit and depressing '1' and '0' keys of the ten-key. For example, in case the 5th digit from the right shown in figure is '1', it represents 'timeout dialing inhibited' and in case it is '0', it represents 'timeout dialing enable', and the 5th digit '1' in the data represents a timeout dialing inhibit data. Thus, the specification of the dialing function is easily revised and even if the specification of the dialing differs from the standards of each country, the system can cope with the revision simply.

Title: Ic card case and ic card
Inventor: KATAKUDA YASUO
IPC: B42D15/10
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To prevent data of an IC card or an IC chip from being destroyed by storing an IC card in an IC card case and permitting an electromagnetic shielding means to shield an electromagnetic wave even if it is radiated. SOLUTION: The IC card case 1 is composed of a transparent film 2, nonwoven fabric and a cover part 4. Nonwoven fabric is obtained by mixing fiber-like plastic and metallic fiber as the electromagnetic shielding means and compressing it in a sheet form for forming the bag of the IC card case 1, for example. Thus, electromagnetic introduction to the IC card by an electromagnetic wave is prevented by containing metallic fiber having electric conductivity as a conductive member. The cover part 4 is peeled off so that it cannot be adhered again at the time of opening. When the IC card is stored in the IC card case 1, the electromagnetic wave is shielded by the metallic fiber of nonwoven fabric even if it is radiated. The influence of the harmful electromagnetic wave such as the destruction of data in the IC card or the IC chip is not given at the time of storing the IC card.
